Original HP 1963 Corvette T-10 four speed Aluminum case with partial VIN Small input bearing retainer This is the HIGH PERFORMANCE 2.20 first gear transmission originally from the Vettes equipped with 340 horsepower 327 four barrel or the 360 horsepower fuelie 327. Spins nice in all gears, some blue RTV present from someone reassembling it but I do not know actual condition. It may be rebuilt or it may need a rebuild. ***ONE YEAR ONLY TRANNY*** Included: - One year only aluminum "421" bellhousing necessary for use with this transmission. Input bearing hole size is smaller for use with this one year only transmission - factory Corvette lightened steel flywheel and new clutch set. I don’t have the part number handy. - shifter and linkage. I believe it is a Mr Gasket shifter from the 60's. Shifter top was cut off, enough to weld back onto. High quality but not a Corvette part. This combination will fit any small block Chevy but is correct for the 1963 Chevy Corvette.
